Brief Description

The ZSPM1000 is a configurable true-digital single-

phase PWM controller for high-current, non-isolated

DC/DC supplies. It operates as a synchronous step-

down converter in a single-rail and single-phase con-

figuration.

The ZSPM1000 integrates a digital control loop, opti-

mized for maximum flexibility and stability, as well as

load step and steady-state performance. In addition,

a rich set of protection and monitoring functions is

provided. On-chip, non-volatile memory (NVM) and

The PC-based ZMDI

’s Pink Power Designer™ pro-

vides a user-friendly and easy-to-use interface to the

device for communication and configuration. It can

guide the user through the design of the digital com-

pensator and offers intuitive configuration methods

for additional features, such as protection and

sequencing.
